Fair enough. I see where you're coming from. Other people think non-scientific debate can be valuable. So I wouldn't propose that we limit debate to the degree you'd like.
It can be valuable, yes. If souls really exist then building a sentient machine might be impossible - and in this respect I'm glad that they were brought up. It is an important point to make. However, in the end, we've got to ask ourselves if there really is any evidence that souls exist - and there isn't. So when somebody says "X, because Y", Y better have some backing.. as in, evidence, hard data, etc. If it's just something pulled out of thin air with no backing at all, then X becomes meaningless and doesn't add to the discussion.
Bringing up theological ideas such as souls is not the problem. The problem is using unsubstantiated claims to back up other claims.. such as - "You can't build a sentient machine since souls exist". Alright, but do they exist? Where is the evidence that they do?

I did start by saying "I think" and mentioned "in my opinion". So while it isn't 'evidence' that part is not circular logic, just an opinion.
It's an opinion based on circular logic. "I think X because of Y because of X". But that point is moot.. I respect your opinion and all, but it would be nice if you showed us how you reached that conclusion - especially since there isn't any evidence to back up what you're saying.
I can easily say "it's impossible for humans to fly to mars and live there". That's my opinion and I'm entitled to it. But if I'm unable to explain how I reached that conclusion, my point won't be taken very seriously.

If you don't know what you're talking about, it's better not to speak up. Deep Blue was not brute force. Deep Blue had databases of openings, end games and a pletora of games played by Grand Masters, including Kasparov himself.
Computer chess programs are often amazingly creative, finding solutions nobody else would have thought of. And they always use reasoning and logic.
You're the one who doesn't understand how Deep Blue works.

The system derives its playing strength mainly out of brute force computing power. It is a massively parallel, 30-node, RS/6000, SP-based computer system enhanced with 480 special purpose VLSI chess chips. Its chess playing program is written in C and ran under the AIX operating system. It was capable of evaluating 200,000,000 positions per second, twice as fast as the 1996 version.

By definition, any discussion of such things as 'intelligence' or 'consciousness' will be supernatural, as there is currently no scientific basis for these notions.
There has been a lot of scientific work done in the areas of intelligence and consciousness. There are no clear answers, sure, but we do have some ideas about these things.. And they do not involve the supernatural in any way!
Bringing the supernatural into play whenever you're stuck and can't fully explain a problem, is a cop-out. Thousands of years ago people didn't understand what stars were - they couldn't explain them, so they attributed them to various Gods. Volcanos? Oh, those were sent by Gods to punish us. Floods? Same thing. How did humans get here? Gods built us! Why are we intelligent? Zeus said so.
Cop-out.

So, I asked myself, what truly is the difference between humans and animals.
I don't mean to nit-pick, but.. we are animals
As for the difference between us and the other animals, I think you're sort of right. IMO, we're able to look at a situation and reason about it. We're also able to take 2 distinct concepts and merge them into an entirely new concept - I don't think any other animal can do this.
All in all there are various degrees of intelligence - and we just happen to be at the top of the pile - as far as life on this planet is concerned anyway.

You need to stop trusting wikipedia, the least reliable source of information anywhere on the web.
No offense, but I'd rather trust wikipedia than you.
You're totally wrong about Deep Blue not using a brute force approach. It does!
This goes back to what I was talking about before - anybody can make a wild claim without backing it up. "Deep Blue doesn't use brute force!". But unless you can back this statement up you're not adding anything of significance to the discussion. If you could find some hard data showing that Deep Blue does not use a brute force algorithm as the basis for its chess-playing mastery, then this conversation would turn into something 10x times as interesting! But until you can do that, nobody's going to take what you say on your faith alone. (Unless they believe the exact same thing, of course)
